DETAILED ACTION Continued Examination Under 37 CFR 1.114 A request for continued examination under 37 CFR 1.114, including the fee set forth in 37 CFR 1.17(e), was filed in this application after allowance or after an Office action under Ex Parte Quayle, 25 USPQ 74, 453 O.G. 213 (Comm'r Pat. 1935). Since this application is eligible for continued examination under 37 CFR 1.114, and the fee set forth in 37 CFR 1.17(e) has been timely paid, prosecution in this application has been reopened pursuant to 37 CFR 1.114. Applicant's submission filed on 6/15/2026 has been entered. Notice of Pre-AIA or AIA Status The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA . Claim Rejections - 35 USC § 102 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action: A person shall be entitled to a patent unless – (a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention. Claim(s) 13-19 is/are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Yaremenko (US20110272413). 13. (Original) A collapsible fuel container (Figs. 1-10, paragraph 0032) comprising: a container body (14) defining an exterior body of the collapsible fuel container; an inner bladder (12) defining a hollow interior, the inner bladder being disposed within the container body and configured to be filled with a fuel and expanded (paragraph 0032); a body restraint harness assembly (18), the body restraint harness assembly being secured to an exterior portion of the inner bladder (and outer bladder) and substantially preventing at least one of vibrations or g-forces through the collapsible fuel container (by securing the container against vibrations); and a tiedown harness assembly (18), the tiedown harness assembly being disposed about an exterior portion of the container body (Fig. 4) and being configured to secure the collapsible fuel container to a platform (Fig. 4). 14. (Original) The collapsible fuel container of claim 13, wherein the body restraint harness assembly includes one or more lateral restraint harnesses that extend along a length of the inner bladder and one or more radial restraint harnesses that extend along a width of the inner bladder (see harness 18, where it extends laterally across the top of the container). 15. (Original) The collapsible fuel container of claim 14, wherein the one or more lateral restraint harnesses include two or more lateral restraint harnesses spaced radially along the inner bladder (see Fig. 3 for the harnesses). 16. (Original) The collapsible fuel container of claim 15, wherein the one or more radial restraint harnesses include two or more radial restraint harnesses spaced laterally along the inner bladder such that the two or more radial restraint harnesses are substantially square with the two or more lateral restraint harnesses (see harness 18, where it extends laterally across the top of the container and Fig. 3). 17. (Original) The collapsible fuel container of claim 13, wherein the tiedown harness assembly includes one or more lateral tiedown harnesses and one or more radial tiedown harnesses (see harness 18, where it extends laterally across the top of the container). 18.

(Original) The collapsible fuel container of claim 18, further comprising a fill assembly configured to direct the fuel into the inner bladder and a vent assembly configured to vent vapors from the inner bladder, wherein the one or more lateral tiedown harnesses extend at an angle away from the fill assembly and the vent assembly (paragraph 0032). Claim Rejections - 35 USC § 103 In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status. The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. Claim(s) 1-12 and 20-38 is/are rejected under 35 U.S.C. 103 as being unpatentable over Yaremenko (US20110272413). 1. Yaremenko teaches a collapsible fuel container (Figs. 1-10, paragraph 0032) comprising: a container body (14) defining a exterior body of the collapsible fuel container, wherein the container body is made of a material that is resistant to punctures from high velocity projectiles (the material is resistant to punctures of projectiles, depending on the force) and is configured to be collapsed and condensed (paraph 0032); and an inner bladder (12) defining a hollow interior, the inner bladder being disposed within the container body and configured to be filled with a fuel and expanded (paragraph 0032). Yaremenko DIFFERS in that it does not disclose the container body and the inner bladder together are resistant to the high velocity projectiles up to 600 ft/s without puncturing the inner bladder. However, it has been held that where the general conditions of a claim are disclosed in the prior art, discovering the optimum or workable values involves only routine skill in the art. In re Aller, 220 F.2d 454, 456, 105 USPQ 233, 235 (CCPA 1955). Therefore, discovering an optimal or workable range is within the skill level of one of ordinary skill within the art. It would have been obvious to, one of ordinary skill within the art, at the time the invention was made, to employ the container to withstand such a velocity projectile, in order to have a container that has the desired strength needed by a consumer. 2. (Original) The collapsible fuel container of claim 1, Yaremenko DIFFERS in that it does not disclose the container body is made of a poly-para-phenylene terephthalamide material. It has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. Therefore, it would have been obvious to, one of ordinary skill within the art, at the time the invention was made, to employ the container of such a material, in order to have a high strength container. 3. (Original) The collapsible fuel container of claim 1, Yaremenko DIFFERS in that it does not disclose the container body includes a coating of thermoplastic urethane. Official Notice is taken that it is old and well known to coat containers with thermoplastic urethane. Therefore, it would have been obvious to, one of ordinary skill within the art, at the time the invention was made, to employ the container of such a coating, in order to have a protective outer layer. 4. (Original) The collapsible fuel container of claim 1, Yaremenko DIFFERS in that it does not disclose the inner bladder is made of nylon. It has been held to be within the general skill of a worker in the art to select a known material on the basis of its suitability for the intended use as a matter of obvious design choice. In re Leshin, 125 USPQ 416. Therefore, it would have been obvious to, one of ordinary skill within the art, at the time the invention was made, to employ the container of such a material, in order to have a high strength container. 5. (Original) The collapsible fuel container of claim 1, further comprising a body restraint harness assembly disposed about an exterior portion of the inner bladder, the body restraint harness assembly being configured to substantially prevent at least one of vibrations or g-forces through the inner bladder (where the container is capable of such). 6. (Original) The collapsible fuel container of claim 5, wherein the body restraint harness assembly includes one or more lateral restraint harnesses that extend along a length of the inner bladder and one or more radial restraint harnesses that extend along a width of the inner bladder (harness extends outside outer and inner blader). 7.
